trident

Uttarakashi - Opposite to Kashi Vishwanath temple there is a temple of Parvati Mata in which there is a huge trident (trishul). Nobody knows how old it is nor are they able to find its depth. Scientists have also failed to recognize what metal it is built of. The story says it is Devi's trishul and it is so deep it goes to patal loka. Its size and weight is so much that it may become difficult to move but then it is possible to shake it with one finger! It's magical!
